Journalling doesn’t appear to be working on an ext3 file-system. When booting, the following line appears:

VFS: Mounted root (ext2 filesystem) readonly.

What could be causing the problem?

A.
An old version of e2fsprogs is installed.

B.
The kernel does not contain ext3 support.

C.
The file-system is specified as ext2 in/etc/fstab.

D.
The system was not shut down cleanly.
